c#：将excel工作簿复制到其他工作簿

我已经编写了将工作表副本复制到新excel文件的代码。下面是我的C#代码，问题是缺少一些命名单元格，我在Excel-2010中对此进行了检查

C#代码：

如果需要复制命名的单元格，可以使用以下代码示例

Sub Copy_All_Defined_Names()
   ' Loop through all of the defined names in the active
   ' workbook.
     For Each x In ActiveWorkbook.Names
      ' Add each defined name from the active workbook to
      ' the target workbook ("Book2.xls" or "Book2.xlsm").
      ' "x.value" refers to the cell references the
      ' defined name points to.
      Workbooks("Book2.xls").Names.Add Name:=x.Name, _
         RefersTo:=x.Value
   Next x
End Sub

缺少的单元格有什么独特之处？我们在工作表中命名了单元格，与默认的A1、A2 s不同。单元格名称类似于“Doc.A.1”等。

Sub Copy_All_Defined_Names()
   ' Loop through all of the defined names in the active
   ' workbook.
     For Each x In ActiveWorkbook.Names
      ' Add each defined name from the active workbook to
      ' the target workbook ("Book2.xls" or "Book2.xlsm").
      ' "x.value" refers to the cell references the
      ' defined name points to.
      Workbooks("Book2.xls").Names.Add Name:=x.Name, _
         RefersTo:=x.Value
   Next x
End Sub
